With properly calibrated tools your bolted connections will always be tightened safely and precisely. Our calibration unit calibrates all torque tools, transducers, torque testers and pump units, regardless of the brand or model.

Our calibration laboratory has been granted the only accreditation for torque in Finland which meets the SFS-EN ISO / IEC 17025: 2017 requirement. Our accreditation code is K060. Accreditation has been granted by FINAS, the national accreditation body in Finland, which supervises the standard compliance of our operations through annual audits. The wide scope of our accreditation includes:

  • Hand torque tools 0,04 – 3 000 Nm
  • Hydraulic torque wrenches 30 – 100 000 Nm
  • Torque transducers and testers 0,04 – 1 500 Nm
  • Electrical torque indicators 0,5 – 11 mV dc

The accreditation also applies to on-site calibrations for hand torque tools and hydraulic torque wrenches, which enables calibrations to be performed directly at the customer’s premises. The calibration service also includes tracking of tool calibration intervals in our system.
